You're doing well not to be just sobbing in the corner this soon after your break up!
You're focussing on the mortgage, but I suspect that's not what's worrying you really.
it's a big change from how you thought your life was going, partner, young child, life plans. You didn't set out to raise a child by yourself.
your financial situation is actually very good.
yes, it seems like a lot of money to owe, especially when you're single (me too) but you need to remind yourself it's a mortgage against an asset, it's security, you have more equity than debt and you have the money to over pay.
although over paying may not be the best move. I save instead of overpaying as it's a better interest rate and I like having the money to use as I need to. I'm not in a huge hurry to pay the mortgage off. And if I want I could pay a lump sum off but I'd rather have the cash available to do some renovations etc
Spend a bit of time making the house YOURS, (one of the silver linings to being single), enjoy your DD & give your brain sometime to come to term with the changes & work out what you're struggling with, because it absolutely doesn't need to be your mortgage 🌷
